Olivia is a 1983 American psychological thriller film directed by Ulli Lommel and starring Suzanna Love and Robert Walker Jr. It follows a young wife in London who is suffering from homicidal schizophrenia, stemming from having witnessed her prostitute mother's murder. She meets an American engineer and has a brief but heated romance with him, and, several years later in Arizona, he encounters a woman who resembles her but claims not to remember him.

Co-written by Lommel and John Marsh, the screenplay was based on a short film Marsh had directed, which was adapted from a short story by the French writer Guy de Maupassant.

Internationally, Olivia was released under the alternate titles Prozzie and Double Jeopardy. In the United States, the film's distributor, Ambassador Films, released it under the alternate title A Taste of Sin.
